Evolution of the international air transportation country network from 2002 to 2013

In this research, we analyze the evolution of the international air transportation country network from 2002 to 2013 with two perspectives: The network’s physical topology and the functional network with traffic information. Our analysis shows that the network is scale-free and has the small-world property. The evolution of triadic properties suggests that the network gears towards symmetric, transitive closure. We find that United States, Great Britain, and France are critical from both perspectives; Surprisingly, South Africa is particularly critical from topological point of view. Furthermore, topological and functional criticality are highly correlated to the GDP of a country.

China’s telecommunications evolution,institutions, and policy issues on the eve of 5G: A two-decade retrospect and prospect

Over the past two decades, China’s telecommunications industry has witnessed drastic market reform, steadfast institutionalization, and volatile technological changes, which have driven exponential industry expansion. This paper offers an updated longitudinal and comprehensive review on this reform process on the eve of 5G (the fifth generation mobile communications networks). First, the paper segments the two-decade reform crusade into discernible phases, each of which is embedded with different policy drives. These reform phases are then pattern-matched against the subtleties of the overall institutional, technological, and market backdrop. A series of policy issues are identified through a systematic examination of industry phenomena over the reform course. Finally, the status of research is assessed regarding China’s telecom industry and reform, based on which, knowledge gaps are identified and future research agenda suggested. Conclusions are made regarding future reform and research imperatives. The paper advances the understanding of China’s telecom reform, development, and the underlying policy issues. It updates and expands previous works on similar topics. Overall, this study provides important theoretical, managerial, and policy implications.     

Quantifying land-use change impacts on the dynamic evolution of flood vulnerability

Recently, dramatic flood disasters have occurred incrementally in several regions of the world. Land-use change as one of the main affecting factors becomes a key component in flood risk management. This study strives to deal with quantifying how changes in land use to affect the dynamic evolution of flood vulnerability. The floodplains of Wuhan, which are located in the Yangtze River Basin, have been selected as an example. In this paper, we use GIS to gather different historical geometric data as sources of land-use information. By proposing the Simpsons-dominance index and location index to analyze the characteristics of land-use changes, and building a quantitative model to measure flood vulnerability, a series of flood vulnerability maps demonstrate differential flood vulnerability of floodplains of Wuhan in three inundation scenarios and four historical periods. Finally, the non-parametric correlation is used to reveal the interactive effect of land use and flood vulnerability. Based on this study, comprehensive flood disaster management strategies for land-use planning are proposed for government decision-makers to reduce the flood vulnerability of Wuhan in future.

The evolution of competition in innovation resource: a theoretical study based on Lotka–Volterra model

This research uses the Lotka–Volterra model to analyse the competition of innovation resource between two enterprises and studies the dynamic effects of environmental changes through the change of model parameters. The research finds that there are three possible results of the competition in innovation resource. That comprises ‘crowding out effect’, ‘unstable equilibrium’ and ‘stable equilibrium’. The results of competitive evolution are determined by enterprises’ interaction parameters. However, the natural growth rates, the initial resource possessions of both enterprises and the amount of regional innovation resource have a significant impact on the evolution of competition.     

Structural production layer decomposition: a new method to measure differences between MRIO databases for footprint assessments

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input–output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint. Using the carbon footprint of the EU-28 in 2011 as an example, we analyse the differences between EXIOBASE, Eora, GTAP and WIOD. Identical environmental data are used across all MRIO databases. In all model comparisons, variations in domestic blocks have a more significant impact on the carbon footprint than variations in trade blocks. The results provide a wealth of information for MRIO developers and are relevant for policy makers designing climate policy measures targeted to specific stages along product supply chains.

Competing technologies and industry evolution: The benefits of making mistakes in the flat panel display industry

This article investigates the post‐entry implications of pre‐entry technological choices made during the uncertain period before a dominant design. Building on work on technological dynamics and organizational inertia, I argue that too early commitments to the winning technology may impede the ability to bring the best product to market, but delaying investment too long limits the ability to accumulate useful knowledge. Using data from the evolution of the flat panel display industry from 1965 to 2005, the study shows empirical support for the two theoretical mechanisms and offers the surprising result that firms starting in the losing technology before switching outperform other firms in terms of product value. Switching, while difficult behaviorally in recovering from failure, both delays difficult‐to‐reverse technological commitments and develops market knowledge.
